It doesn’t take much to imagine what a Christopher Nolan war film might be like — epic, visually stunning, and supremely intense. Dunkirk seemingly checks off all of those boxes and then some in the first full-length trailer for Nolan’s highly-anticipated new film, a historical period drama that looks surprisingly claustrophobic given the open setting. Featuring an excellent ensemble of stars (including Tom Hardy and Mark Rylance), Dunkirk doesn’t feel like your average summer film, which has us all the more excited to see it in July.

Hard to believe it, but yes, Dunkirk hits theaters in just a couple of months, giving us our first Nolan film since 2014’s Interstellar. This time, the iconic filmmaker heads back to Earth and back in time to 1940 to recount the harrowing story of the mission to evacuate Allies soldiers from the beaches of France during World War II:

Dunkirk opens as hundreds of thousands of British and Allied troops are surrounded by enemy forces. Trapped on the beach with their backs to the sea they face an impossible situation as the enemy closes in.

Nolan’s latest also stars Kenneth Branagh, Cillian Murphy, James D’Arcy, Fionn Whitehead, and Harry Styles (yes, as in that Harry Styles), and arrives in theaters (and IMAX, of course) on July 21.
